About the mentor

Paul Brook is an investment banker and merchant banker with approximately 30 years of experience spanning institutional investment banking, private capital, special situations, and strategic advisory. His career includes senior roles at Lehman Brothers, Nomura Holdings, Barclays Corporate, and National Australia Bank, as well as independent advisory mandates he has led across Asia, Australia, Europe, and the Americas.

He has sat on trading floors, pitched boards, built client books from scratch, navigated restructurings, executed cross-border transactions exceeding US$6bn in aggregate value, and run his own advisory business — including one he built and sold to private equity. 

Brook has operated through every major market dislocation of the past three decades — the Asian Financial Crisis, the dot-com correction, the Global Financial Crisis (from within Lehman Brothers, subsequently managing franchise stability and client continuity through the Nomura integration), and the COVID disruption. That depth of cycle experience informs both how he evaluates opportunities and the practical advice he offers to professionals navigating uncertain markets.

Brook is happy to mentor professionals at any career stage — whether you're breaking into banking, navigating a lateral move, thinking about the buy side, considering independent advisory work, or figuring out how to build a career across multiple geographies. He has done most of it and is straightforward about what works and what doesn't.
